• 用 Apache Airflow 编排大型和小型项目
  • REAL PYTHON
  • PODCAST

Have you worked on a project that needed an orchestration tool? How do you define the workflow of an entire data pipeline or a messaging system with Python? This week on the show, Calvin Hendryx-Parker is back to talk about using Apache Airflow and orchestrating Python projects.

(是也乎:

什么是编排? 为什么数据/消息的流通会变来变去?

探讨/吐糟

Discussions

• 关于 Python 打包生态系统的思考
  • HACKER NEWS

There’s been lots of chatter about packaging in Python of late, this discussion centers around Pradyun Gedam’s excellent article. For more on the same topic see last issue’s How to improve Python packaging, or why fourteen tools are at least twelve too many as well.

• Breaking the Snake: Python 如何从 2 到 3
  • HACKER NEWS

This discussion spawned from Diego Crespo’s article of the same name talks about the transition that somehow everyone is still interested in talking about.

文章/教程/嗯哼

Articles, Tutorials and Talks

• Python 标准 REPL: 快速尝试代码和想法
  • REAL PYTHON

In this tutorial, you’ll learn how to use the Python standard REPL (Read-Eval-Print Loop) to run your code interactively. This tool will allow you to test new ideas, explore and experiment with new tools and libraries, refactor and debug your code, try out examples, and more.

(是也乎:

REPL 的确是 Python 一大特色, 以往只有 数据库产品才有...

• Python 中的线性代数: 矩阵求逆和最小二乘法
  • REAL PYTHON

In this tutorial, you’ll work with linear algebra in Python. You’ll learn how to perform computations on matrices and vectors, how to study linear systems and solve them using matrix inverses, and how to perform linear regression to predict prices based on historical data.

(是也乎:

大学高等数学没通的, 看了也白看...

• Python 中的距离和接近度分析
  • KYLE WALKER

“Spatial data science projects frequently require the calculation of proximity to resources.” This article shows you how to calculate proximity in Python code using two different techniques: Euclidean and driving times. Examples use geopandas and routingpy packages.

• 我在 20 年的软件工程师生涯中学到的 20 件事
  • JUSTIN ETHEREDGE

Justin writes a list of things he has learned over his past 20 years in development. He starts by stating how context is important and that his lessons are from small teams with an emphasis on productivity and being tool agnostic.

(是也乎:

20年程序猿生涯的感悟...

对于俺,只有一条: 跟对人, 跟得上 足以飞升

• Python 中的单引号 (') 或双引号 (") 到底怎么搞?
  • MEDIUM.COM/PYTHONIQ
  • • Shared by Marcin

The article addresses the following question. Many claim you should prefer single over double quotes in Python. Should you?

20 条偈语，有关构建更好的软件, 适用一切语言/技术桟:

Optimize for simplicity first
Write code for humans, not computers
Reading is more important than writing
Any style is fine, as long as it’s black
There should be one way to do it, but seriously this time
Hide the sharp knives
Changing the rules is better than adding exceptions
Libraries are better than frameworks
Transitive dependencies are a problem
Dynamic runtime dependencies are a bigger problem
API surface area is a liability
Returning early is a good thing
Use more plain text
Compiler errors are better than runtime errors
Runtime errors are better than bugs
Tooling is better than documentation
Documentation is better than nothing
Configuration sucks, but so does convention
The cost of building a feature is its smallest cost
Types are one honking great idea – let’s do more of those!

不觉中蟒周刊快译已经到了第11个年头

开始有小伙伴加入承担 pythonisa 周刊的翻译, 从来没提醒过, 可就这么默默坚持下来了...

问为什么:

[皱眉]每周新闻资讯 怎么能错过 
看看有什么新东西 
当有新的发现时：
    what f**k 还能这样玩？ 还有这东西？
    每周开彩蛋[吃瓜]

无法同意更多... 很多社区贡献看起来辛苦, 其实受益最多的, 就是主动承担者也.
